KICKBACK
WARNING: Avoid kickback which
can result in serious injury. Kickback is the
backward, upwardorsuddenforwardmotion
of the guide bar occurring when the saw
chainneartheupper tip oftheguide barcontacts any object such as a log or branch, or
when the wood closes in and pinches the
saw chain in thecut.Contactingaforeignobject in the wood can also result in loss of
chain saw control.
S Rotational Kickback can occurwhenthe
moving chain contacts an objectat theupper tip of the guide bar. This contact can
cause the chain to dig into the object,
which stops the chain for an instant. The
result is a lightning fast, reverse reaction
which kicks the guide bar up and back toward the operator.
S Pinch-Kickback can occur when the the
wood closes in and pinches the moving
saw chain in the cut along the top of the
guide bar and the saw chain is suddenly
stopped. This sudden stopping of the
chain results in a reversal of the chain
force used to cut wood and causes the
sawtomove inthe opposite direction ofthe
chain rotation. The saw is driven straight
back toward the operator.
S Pull-In can occur when the moving chain
contacts a foreign object in the wood in the
cut along the bottom of the guide bar and
the saw chain is suddenly stopped. This
suddenstoppingpulls thesaw forwardand
away from the operator and could easily
cause the operator to lose control of the
saw.
Avoid Pinch--Kickback:
S Be extremely aware of situations or ob-
structions thatcan cause material topinch
the top of or otherwise stop the chain.
S Do not cut more than one log at a time.
S Do not twist the saw as the bar is with-
drawn from an undercut when bucking.
Avoid Pull--In:
S Always begin cuttingwith the engine at full
speed and the saw housing againstwood.
S Use wedges made of plastic or wood.
Never use metal to hold the cut open.

Avoid obstructions
Clear the
working area
REDUCETHECHANCEOF
KICKBACK
S Recognize that kickback can happen.
With a basic understanding of kickback,
you can reduce the element of surprise
which contributes to accidents.
S Neverletthemoving chain contactany ob-
ject at the tip of the guide bar.
S Keep the working area free from obstruc-
tionssuchas othertrees,branches,rocks,
fences, stumps, etc. Eliminate or avoid
any obstruction that your saw chain could
hit while you are cutting through a particular log or branch.
S Keep your saw chain sharp and properly
tensioned. A loose or dull chain can increase the chance of kickback occurring.
Follow manufacturer’s chain sharpening
andmaintenanceinstructions. Checktension at regular intervals with the engine
stopped, never with the engine running.
Makesure thebarclampnuts aresecurely
tightened after tensioning the chain.
S Begin and continue cutting at full speed. If
the chain is moving at a slower speed, there
is greater chance of kickback occurring.
S Cut one log at a time.
S Use extreme caution when re-entering a
previous cut.
S Do not attempt cuts starting with the tip of
the bar (plunge cuts).
S Watch for shifting logs or other forces that
could close a cut and pinch or fall into chain.
S Use the Reduced--Kickback Guide Bar and
Low- -Kickback Chain specified for your saw.

S Keep a good, firm gripon the saw with both
hands when the engine is running and
don’tlet go. Afirmgrip will help youreduce
kickback and maintain control of the saw.
Keep the fingers of your left hand encircling and your left thumb under the front
handlebar. Keep your right hand completely around the rear handle whether
your arerighthandedorlefthanded. Keep
your left arm straight with the elbow
locked.
S Positionyour left hand on the fronthandle-
bar so it is in a straight line with your right
hand on the rear handle when making
bucking cuts. Never reverse right and left
hand positions for any type of cutting.
S Stand withyourweightevenly balancedon
both feet.
S Stand slightly to the left side of the saw to
keep your body from being in a direct line
with the cutting chain.
S Do not overreach. Youcould be drawn or
thrown off balance and lose control of the
saw.
S Do not cut above shoulderheight. Itis diffi-
cult to maintain control of saw above
shoulder height.
KICKBACK SAFETY FEATURES
WARNING: The following features are
included on your saw to help reduce the hazard
of kickback; however, such features will not totally eliminate this dangerous reaction. As a
chain saw user, do not rely only on safety devices. You must follow all safety precautions,
instructions, and maintenance in this manualto
help avoid kickback and other forces which
can result in serious injury.
S Reduced--Kickback Guide Bar, designed

WARNING: DO NOT RELY UPON
ANYO F THE DEVICES BUILTINTOYOUR
SAW. YOU SHOULD USE THE SAW
PROPERLY AND CAREFULLY TO AVOID
KICKBACK. Reduced--kickback guide bars
and low--kickback saw chains reduce the
chance and magnitude of kickback and are
recommended. Yoursaw has a low kickback
chain and bar as original equipment. Repairs onachainbrake should be made by an
authorized servicingdealer.Takeyour unitto

will need to tighten chain brake nuts.
CHAIN TENSION (Including units
with chain already installed)
NOTE
: When adjusting chain tension, make
sure the chain brake nuts are finger tight only.
Attempting to tension the chain when the chain
brake nuts are tight can cause damage.
Checking the tension:
Use the screwdriver end of the chain adjustment tool (bar tool) to move the chain around
the bar. If the chain does not rotate, it is too
tight. If too loose, the chain will sag below the
bar.
Chain Brake Nuts
Adjusting the tension:
Chain tension is very important. Chain
stretches during use. This is especially true
during the first few times you use your saw.
Always check chain tension each time you
use and refuel your saw. Youcan adjust the
chain tension by loosening the chain brake
nuts and turning the adjusting screw 1/4 of a
turn while lifting up on the bar.

WARNING: Be sure to read the fuel
informationinthe safety rules before youbegin.Ifyoudonot understand thesafety rules,
do not attempt to fuel your unit. Contact an
authorized service dealer.
BAR AND CHAIN LUBRICATION
The bar and chain require continuous lubrication. Lubrication is provided by the automatic oiler system when the oil tank is kept
filled. Lack of oil will quickly ruin the bar and
chain. Too little oil will cause overheating
shown by smoke comingfromthe chain and/
or discoloration of the bar.
Only use Bar and Chain Oil forbar andchain
lubrication.
Oil Cap
FUELING ENGINE
WARNING: Remove fuel cap slowly
when refueling.
This engine is certified to operate on unleaded
gasoline. Before operation, gasoline must be
mixed with a good quality 2-cycle air-cooled
engine oil designed to be mixed at a ratio of
40:1. A 40:1 ratio is obtained by mixing 0,125
liter of oil with 5 liters of unleaded gasoline. DO
NOT USE automotive or boat oil. These oils
will cause engine damage. When mixing fuel
follow the instructions printed on the container.
Always read and follow the safety rules relating
to fuel before fueling your unit.
IMPORTANT
Experience indicates that alcohol blended
fuels (called gasohol or using ethanol or
methanol) can attract moisture which leads
to separation and formation of acids during
storage.Acidicgascandamagethe fuelsys-

CUTTING METHODS
IMPORTANT POINTS
S Check chain tension before first use and
after 1 minute of operation. See CHAIN
TENSION in the ASSEMBLY section.
S Cut wood only. Do not cut metal, plastics,
masonry, non-wood building materials,
etc.
S The bumper spike may be used as a pivot
when making a cut.
S Stop the saw if the chain strikes a foreign
object. Inspectthesawandrepair parts as
necessary.
S Keep thechainout ofdirtand sand. Evena
smallamountof dirt willquickly dull achain
and increase the possibility of kickback.
S Practice cutting a few small logs using the
following techniques toget the “feel” of using your saw before you begin a major
sawing operation.
S Squeeze the throttle trigger and allow the
engine to reach full speed before cutting.
S Begin cutting with the saw frame
against the log.
S Keep the engineat full speed theentire
time you are cutting.
S Allow thechainto cut foryou.Exertonly
light downward pressure.
S Release the throttle trigger as soon as
the cut is completed, allowing the engine to idle. If you run the saw at full
throttlewithout acutting load,unnecessary wear can occur.
S To avoid losing control when cut is com-
plete, do not put pressure on saw at end
of cut.
S Stop the engine before setting the saw
down.
TREE FELLING TECHNIQUES
WARNING: Donotcutnear buildings
or electrical wires if you do not know the direction of tree fall, at night since you will not
be able to see well, or during bad weather
such as rain, snow, or strong winds. as fall is
unpredictable.
Carefully plan your sawing operation in advance. You need a clear area all around the
tree so youcan have secure footing. Check
for broken or dead branches which can fall
on you causing serious injury.
Natural conditions that can cause a tree to
fall in a particular direction include:
S The wind direction and speed.
S The lean of the tree. The lean of a tree
might not be apparent due to uneven or
slopingterrain. Use aplumborlevel to determine the direction of tree lean.
S Weight and branches on one side.
S Surrounding trees and obstacles.
Look for decay and rot. Ifthe trunk is rotted,
it can snap and fall toward the operator.
Make sure there is enough room for the tree to
fall. Maintain a distance of
from the nearest person or other objects. Engine noise can drown out a warning call.
2-1/2 tree lengths
Remove dirt, stones, loose bark, nails, staples,
and wire from the tree where cuts are to be
made.

will tend to fall into the notch.
NOTCH CUT AND FELLING THE
TREE
S Make notch cut by cutting the top of the
notch first. Cut through
ofthe tree. Nextcomplete thenotchbycutting the bottom of the notch. See illustration. Once the notch is cut remove the
notch of wood from the tree.
First cut
Notch
Second cut
S After removing the wood from the notch,
makethefellingcut on the opposite sideof
the notch. This is done by making a cut
about two inches higher than the center of
the notch. This will leave enough uncut
woodbetweenthefelling cutandthe notch
to form a hinge. This hinge will help preventthe treefromfalling in thewrongdirection.
Hinge holds tree on stump and helps
control fall

NOTE: Before felling cut is complete, use
wedges to open the cut when necessary to
controlthedirectionoffall. Toavoidkickback
or chain damage, use wood or plastic
wedges, but never steel or iron wedges.

S Be alert to signs that the tree is ready to
fall: cracking sounds, widening of the felling cut, or movement in the upper
branches.
S As tree starts to fall, stop saw, put itdown,
and get away quickly on your planned retreat path.
S DO NOT cut down a partially fallen tree
withyour saw. Beextremely cautiouswith
partially fallen trees that may be poorly
supported. When a tree doesn’t fall completely,setthesaw asideandpulldownthe
tree with a cable winch, block and tackle,
or tractor.
CUTTING A FALLEN TREE
(BUCKING)
Bucking is the term used for cutting a fallen
tree to the desired log length.
WARNING: Do not stand on the log
being cut. Any portion can roll causing loss
of footing and control. Do not stand downhill
of the log being cut.
Important points
S Cut only one log at a time.
S Cut shattered wood very carefully; sharp
piecesofwood could beflungtowardoperator.
S Use a sawhorse to cut small logs. Never
allow another person to hold the log while
cuttingandnever holdthelogwithyour leg
or foot.
S Do not cut in an area where logs, limbs,
and roots are tangled. Drag the logs into a
clear area before cutting by pulling out exposed and cleared logs first.
TYPES OF CUTTING USED FOR
BUCKING
WARNING: If saw becomes pinched
or hung in a log, don’t try to force it out. You
can lose control of the saw resulting in injury
and/or damage to the saw. Stop the saw,
drive a wedge of plastic or wood into the cut
untilthesawcan beremovedeasily. Restart
thesaw andcarefully reenter the cut. Donot
attemptto restart your saw whenitispinched
or hung in a log.
WARNING: Never turn saw upside
down to undercut. The saw cannot be controlled in this position.
First cut on pressure side of log
Second cut
First cut on pressure side of log
Second cut
BUCKING WITHOUT A
SUPPORT
S Overcut through 1/3 of the diameter of the
log.
S Roll the log over and finish with a second
overcut.
S Give special attention to logs under strain
to prevent the saw from pinching. Make
the first cut onthe pressure side to relieve
the stress on the log.
BUCKING USING A LOG OR SUPPORT STAND
S Remember your first cut is always on the
pressure side of the log.
S Your first cut should extend
diameter of the log.
S Finish with your second cut.

LIMBING AND PRUNING
WARNING: Be alert for and guard
against kickback. Do not allow the moving
chain to contact any other branched or objects
at the nose of the guide bar when limbing or
pruning. Allowing such contact can result in
serious injury.
WARNING: Neverclimbintoatreeto
limb or prune. Do not stand on ladders, platforms, a log, or in any position whichcan cause
you to lose your balance or control of the saw.
IMPORTANT POINTS
S Watch out for springpoles. Use extreme
caution when cutting small size limbs. Slender material may catch the saw chain andbe
whipped toward you or pull you off balance.
S Be alert for springback. Watch out for
branches that are bent or under pressure.
Avoid being struck by the branch or the
saw when the tension in the wood fibers is
released.
S Keep a clear work area. Frequently clear
branches out of the way to avoid tripping
over them.
LIMBING
S Alwayslimbatreeafter it is cut down. Only
then can limbing be done safely and properly.
S Leave the larger limbs underneath the
felled tree to support the tree as you work.
SERVICE AND ADJUSTMENTS
S Start at base of the felledtreeandwork to-
ward the top, cutting branches and limbs.
Remove small limbs with one cut.
S Keep the tree between you and the chain
as much as possible.
S Remove larger, supporting branches with
thecuttingtechniques describedinBUCKING WITHOUT A SUPPORT.
S Always use an overcut to cut small and
freely hanging limbs. Undercutting could
cause limbs to fall and pinch saw.
PRUNING
WARNING: Limit pruning to limbs
shoulder height or below. Do not cut if
branches are higher than your shoulder.Get
a professional to do the job.
S Make your fist cut
the bottom of the limb.
S Next makea 2ndcut all the way through
the limb. Then cut a third overcut leaving

evaporative emissions.
Cleaning the air filter:
A dirty air filter decreases engine performance and increases fuel consumption and
harmful emissions. Always clean after every
5 hours of operation.
1. Clean thecover and the area around it to
keep dirt and sawdust from falling into
the carburetor chamber when the cover
is removed.
2. Remove the parts as illustrated below.
3. Wash the filter in soap and water. Rinse
in clean cool water. Air dry completely
before reinstalling.

BAR MAINTENANCE
If your saw cuts to one side, has to be forced
through the cut, or been run with an improper
amount of bar lubrication it may be necessary
to service your bar.
A worn bar will damage your chain and make
cutting difficult.
After each use, ensure ON/STOP switch is in
theSTOPposition, then clean allsawdust from
the guide bar and sprocket hole.
T o maintain guide bar:
S Move ON/STOP switch to the STOP posi-
tion.
S Loosen and remove chain brake nuts and
chain brake. Remove bar and chain from
saw.
S Clean the oil holes andbargroove aftereach
5 hours of operation.
Remove Sawdust From
Guide Bar Groove
Oil Holes
S Burring of guide bar rails is a normal process
of rail wear. Remove these burrs with a flat
file.
S When rail top is uneven, use a flat file to re-
store square edges and sides.
Worn Groove
Replace guide bar when the groove is worn,
the guide bar is bent or cracked, or whenexcess heating or burring of the rails occurs. If replacement is necessary,use only the guidebar
specified for your saw in the repair parts list or
on the decal located on the chain saw.
SPARK PLUG
The spark plug should be replaced each year
toensure the engine starts easier and runs better. Ignition timing is fixed and nonadjustable.
1. Loosen 3 screws on cylinder cover.
2. Remove the cylinder cover.
3. Pull off the spark plug boot.
4. Remove spark plug from cylinder and discard.
5. Replace with Champion RCJ--7Y spark
plug and tighten securely with a 19 mm

CHAIN SHARPENING
Chain sharpening is a complicated task that
requires specialtools. We recommend thatyou
refer chain sharpening to a professional chain
sharpener.
CARBURE TO R ADJUSTMENT S
WARNING: Thechainwillbemoving
during most of this procedure. Wear your protective equipment and observe all safety precautions. The chain must not move at idle
speed.
The carburetor has been carefully set at the
factory. Adjustments may be necessary if you
notice any of the following conditions:
S Chain moves at idle. See IDLE SPEED--T
adjusting procedure.
S Saw will not idle. See IDLE SPEED--T ad-
justing procedure.
Idle Speed --- T
Allow engine to idle. If the chain moves, idle is
toofast. If the engine stalls, idle is too slow. Adjust speed until engine runs without chain
movement (idle too fast) or stalling (idle too
slow). The idle speed screw is located in the
area above the primer bulb and is labeled T.
S Turn idle speed screw (T) clockwise to in-
crease engine speed.
S Turn idle speed screw (T) counterclockwise
to decrease engine speed.
STORAGE
WARNING: Stop engine and allow to
cool, and secure the unit before storing or
transporting in a vehicle. Store unit and fuel
in an area where fuel vapors cannot reach
sparks or open flames from water heaters,
electric motors or switches, furnaces, etc.
Storeunit withallguards in place. Positionso
that any sharp object cannot accidentally
cause injury to passersby. Store the unit out
of reach of children.
S Before storing, drain all fuel from the unit.
Start engine and allow to run until it stops.
S Clean the unit before storing. Pay particular
attention to the air intake area, keeping it free
of debris. Use a mild detergent and sponge
to clean the plastic surfaces.
S Do not store the unit or fuel in a closed area
where fuel vapors can reach sparks or an
open flame from hot water heaters, electric
motors or switches, furnaces, etc.
S Store in a dry area out of the reach of chil-
dren.
S Ensure the machine is cleaned and that a
complete service is carried out before long- term storage.
S The guide bar and chain must always be
covered with a scabbard when the machine
is being transported or in storage in order to
prevent accident contact with the sharp
chain. Even a non--moving chain can cause
serious cuts to yourself or persons you
bump into with an exposed chain.
